FIELD OF THE INVENTION

The present invention is directed, generally, to implantable ports usedfor intravenous medication administration and methods of using the same.

BACKGROUND OF THE INVENTION

Several publications are referenced in this application. The citedreferences describe the state of the art to which this inventionpertains and are hereby incorporated by reference, particularly thesystems and methods set forth in the detailed description and figures ofeach reference.

A port is a device used in the field of medicine for the administrationof any intravenous medication, namely chemotherapeutics, but otherfrequently administered medications and fluids for a plethora of chronicailments. Similarly, a port device, through its attached catheter,allows for intravenous blood sampling for a variety of laboratory tests.It is a minimally invasive, surgically implanted device, typicallyplaced under the skin of the chest by a physician practicing in the artof surgery, interventional radiology, or other procedural-relatedfields. Specifically, the device comprises two basic components—areservoir placed in the subcutaneous tissues (most commonly of theanterior chest wall) and a contiguous tubular catheter member thatenters the nearby venous bloodstream. This reservoir is covered with aspecialized silicone cap that allows repeated needle access. Thisrequires access by trained personnel with a specialized “non-coring”needle to maintain the integrity of the device, the needle comprising aspecialized tip to prevent tearing of the silicone cap or creation oflarger holes, limiting the lifespan of the device. The reservoirs andcatheters are typically made from biocompatible plastics and/or otherpolymers and/or metals such as titanium. When implanted, the tubularcatheter member typically travels over the clavicle, into the internaljugular vein, and then inferiorly into the superior vena cava where itis intended to terminate near the right atrium. Other, less common, butaccepted port placement locations include the subclavian and externaljugular veins, and deep veins of the upper arm. Exemplary medicationports currently on the market include the PowerPort®, Medi-Port,Port-A-Cath®, Smart Port, and Bioflo. Most port catheters in practiceare of a single-lumen configuration. However, other ports have beendesigned and used with multiple reservoirs and multiluminal catheterarrangements for the infusion of either simultaneous fluids or forfluids required by the patient's condition known to react orprecipitate.

Chemotherapy patients typically have an infusion port placed into thechest via a minor surgical procedure. Ports allow for infusion ofchemotherapy and other medications directly into the central venoussystem (with the catheter tip typically positioned in the superior venacava or right atrium). Ports also allow for blood draws for routine labtests. These devices are useful for any patients that require long-termIV medication, nutrition administration, fluid support, or those withdifficult vascular access. Ports remain sterile under the skin with noexternal features.

Implantable ports have many advantages for use in patients that requirefrequent, repeated administration of intravenous medications. Manymedications are known to cause damage to the vein wall of a peripheralvein, including thrombosis, stenosis, overt occlusion, and/or pain.Additionally, because port devices have a catheter with a relativelylarge lumen resting in the central veins, they offer a means of accurateblood sampling for laboratory testing without a high risk of hemolysis.As a surgically implanted device that resides completely within thebody, ports have a lower risk of infection when compared with otherindwelling venous catheters such as central venous catheters (CVC),peripherally inserted central catheters (PICC), or others such assubcutaneously tunneled and cuffed catheters seen for long-term vascularaccess and dialysis. The method of access is also related with lowerreported perceived pain when compared with a peripheral phlebotomy orplacement of a peripheral IV. For these reasons, ports are the preferredmethod of vascular access for cancer patients requiring chemotherapy aswell as patients with certain additional indications, such as arequirement for long term antibiotic medications in cystic fibrosis,clotting factor replacement and transfusion in hemophilia and otherblood dyscrasias, replacement therapy for alpha 1-antitrypsindeficiency, and administration of analgesics for patients with chronicpain, to name only a few exemplary clinical scenarios.

Although longstanding stalwarts in cancer care, and adequate for thestated function, commercially available ports have several limitations.Because they rest under the skin and within the body, they need to beeasily identifiable for access. Current models contain a reservoir thatis relatively tall and bulky, sometimes with palpable bumps or edges, bypurposeful design, causing a visible and palpable bulge under the skinof the chest. When a skilled healthcare worker needs to access the port,the reservoir is first visualized and then palpated deep to the skin.Once the area is sterilized, a non-coring (Huber) type needle is used toaccess the port through the skin while the substantial device is trappedbetween the fingers of the accessing medical provider. Heretofore, therehas been a clinical need for the port to be visible and palpable, whichhas required placing the device within the chest wall just inferior tothe clavicle. This results in a variable degree of pain or discomfort,cosmetic concerns for the patients, and is a constant reminder of theirdisease process with associated psychosocial considerations. For thesereasons, patients frequently request removal of their port at theearliest possible time, even though it may be recommended to retaintheir port for additional future venous access.

SUMMARY OF THE INVENTION

One aspect of the invention overcomes shortcomings of current devices byallowing for a lower-profile medication port that is nearlyimperceptible by the patient and reduces discomfort.

Another aspect of the invention provides a port that integrateselectronic identification and/or localization tools to ensure accuratepatient and device identification and/or location. This identificationfeature also preferably allows linking of all uses of the port to thatpatient's record for transmission of an accurate record of treatment,for example cancer care. It is believed current ports on the market donot contain any advanced technology beyond those required for vascularaccess and medication administration. Specifically, there are no meansof electronic identification of the device or the patient, orlocalization of the device. Additionally, it is believed, current portshave no technology that allows for physiologic monitoring of thepatient. Given the risks associated with improper patient identificationor medication administration as well as the risk of clinicaldeterioration, applicants have discovered it would be beneficial for anindwelling port to contain advanced electronic identification andmonitoring technology with the capability of transmitting data to aserver-based computing platform, such as an electronic medical record(EMR).

Another aspect of the invention provides a port and method that allowsfor advanced physiologic monitoring. It is believed current ports haveno means of identification, collection of data, or transmission ofinformation. At most, ports may have some minimal degree of metallicmaterial used simply to make it identifiable by radiography, or with theletters “CT” to identify its ability to withstand pressures of aso-called computed tomography (CT) power injection (typically, definedas infusion rates at a minimum of 5 milliliters per second). Thus far,this most basic data is the only information that can be interpretedfrom this device once implanted. The simple contemporary ports containonly the hardware required to infuse medication (or other fluids) andwithdraw blood. As described herein, it is preferable if a medicationport includes embedded identification information about the device, thepatient, and the patient's treatment history which could be extractedelectronically. According to preferred embodiments, the port monitorsorientation and vector acceleration to track patient body orientation,physical activity, exercise, and gait, and to trigger alerts for fallprevention and identification of other characteristically unsafeconditions. This information could advantageously decrease the incidenceof errors of patient identification, medication administrations, andcare management. Additionally, this information could then be linked toevery use of the port so that treatment records and port maintenancecould be stored in a local and/or centralized database and in theelectronic medical record. Such data could be collected at the facilitylevel, or become portable, such that a patient has the ability to obtaincare at more than one facility and maintain a cohesive and completecancer care record. Finally, such transfer of electronic data could beaccessed and managed by the patient for their own understanding andplanning. Preferably, the port is optimized to deliver medications atcontrolled rates or medications of non-traditional types, including stemcell, viral, bacterial, fungal, yeast, protein, DNA, or RNA basedagents. For the purposes of medication delivery, a port may befabricated from permeable or bio-absorbable materials to allow elutionof fluid, gaseous, powdered, granulated, or solid form pharmaceutical orbiologic agents.

Another aspect of the invention relates to improved medication portshaving a low profile, or flattened reservoir compared to current deviceson the market. Preferably, the ratio of height or depth of the devicescompared to the largest width (e.g., rectangular devices) or diameter(e.g., disc-shape) is less than ⅓, even more preferably, less than ¼ andmost preferred less than ⅕. For example, referring to FIG. 2A, thedevice shown has a lower profile (lower height/width ratio) compared tothe taller device in FIG. 1 .

Another aspect of the invention relates to a second device,complementary to the medication port system, which is a handheldidentification device. This device is preferably used by the healthcareprofessional or caregiver to locate the port reservoir as the port ispreferably not easily visualized or palpated due to its preferred lowprofile. According to preferred embodiments, the handheld device hasdetecting electronics that sense the location of the port reservoir inthree-dimensional space, as well as extract the information embeddedwithin the electronics within the port (for example, RFID tags), andalso includes physiologic sensors, or other data storage devicesembedded in the port. Preferred embodiments of the device can also beidentified by a characteristic external shape (e.g. oval, square,round), surface texture, protrusion or bump; or in response to a signal,the device may change its motion state, illumination, shape, orconfiguration of protrusions to indicate device response, change ofstate, or status. For example, the device may vibrate or self-illuminatewhen physically tapped or signaled by the handheld device; or it maychange dimensional aspect ratio or extend a physical protrusion inresponse to a signal from the handheld device.

Once the location of the port is identified by the detection system, thehandheld device provides instructions to the user for preciselocalization for needle access and other actions. These instructions maycomprise audible, visual, or tactile feedback mechanisms, or anycombination thereof. For example, in one embodiment, the handheld deviceis used to remotely power light emitting diodes (LEDs) on the surface orperiphery of the port that transilluminate through the skin. These LEDscan be visualized and aligned with the handheld device for accuratetargeting of the port during needle access. The handheld detector maythen alert the user when the precise location of the port reservoir isidentified. A target, provided by the handheld device, includes anynumber of visual tools that may be employed to guide the user and theaccess needle, including, but not limited to, laser or other illuminatedcross hairs, physical guides on the handheld device, ink markings, orany other means of showing the user where the center of the reservoirinternally rests. The detector is preferred to be a multiuse device thatalso leaves a space or aperture to prepare the overlying skin in asterile manner.

According to yet another aspect of the invention, in addition tolocalizing the port reservoir, the handheld device can preferably alsobe used as a data-retrieval and data-entry tool that then communicateswith the local electronic medical record and/or a centralized,proprietary database that monitors the use of each port. The handhelddevice preferably has a touch-screen interface that provides aninteractive system or means of two-way electronic communication betweenthe user and the system. Preferably, the touch-screen display can assistin the localization and access procedure by displaying instructions forlocalizing the port, as well as anatomic diagrams showing the portlocation within the patient. Once the port is identified, informationregarding that specific port and the patient will be displayed on thescreen. This will allow the user to confirm that the correct patient isin place and the correct port is in use.

Once the port has been accessed, the user can then use the touch-screeninterface on the handheld device to enter information regarding the useof the port and/or interventions being performed during that accesssession. For example, the healthcare professional could enterinformation such as, “port flush,” or “labs drawn for CBC and CMP,” or“chemotherapy infusion, cisplatin 100 mg/m²”. This information is thentransmitted to the electronic medical record (EMR) as well as to aproprietary database that will monitor the use and maintenance of eachport. Preferably, communication between the handheld device and the EMRand the database will be through a known means of wireless communicationsuch as wireless broadband communication (Wi-Fi) or Bluetooth.

Preferably, entry of many additional aspects of patient care may be madethrough this handheld communication device including, but not limited tovital signs, physical exam findings, performance status, lab values,other medication administration such as steroids and antiemetics,adverse chemotherapy reactions, diagnoses including comorbid medicalconditions, allergies, and other patient identifiers like face photosand date of birth, amongst many others. Any physiologic data stored bythe port device can also be extracted by the handheld device andtransmitted to the database and to the EMR. The handheld devicedescribed herein can be a custom designed device or an off-the-shelfsmart device such as a smart phone or tablet computer with custom andproprietary software applications to perform the functions describedherein. Additionally, the port device itself could contain hardware andsoftware required for direct WiFi, Bluetooth, or cellular communication,not requiring the use of a handheld device.

According to preferred embodiments, data collected from the port and thehandheld device is communicated to the EMR for record keeping in theclinic or hospital where therapy is delivered. That data issimultaneously stored in a proprietary and secure database, offsite.Information in this database is preferably used to track a patient'stherapy as well as port maintenance. This information is preferablyaccessible by that patient as well as the patient's healthcare team.Through this database, the patient and their healthcare providers canpreferably be alerted when the port needs to be flushed and/or lockedwith fluids to prevent thrombus, or when the patient is due to have labsdrawn or medication administered. Additionally, the database willpreferably keep an accurate record of every use of the port, whichessentially provides a detailed record of that patient's therapy, givingeach patient ownership of an accurate, individualized, and portablesummary of their cancer care. All storing of information andcommunication is preferably compliant with the Health InsurancePortability and Accountability Act of 1996 (HIPAA) and the system and/ormethods will preferably utilize data security software and hardwareknown in the art to prevent external hacking or other malicious uses ofpatient data. Communication with the electronic medical record mayrequire use of a third-party interface that is HIPAA compliant. The portand/or hand-held device may also utilize redacting software protocols toexclude certain private patient information to enable data transmissionby non-HIPAA compliant software, servers, and networks.

As the amount of stored treatment and physiologic data increases,database analytics will be applied in a way that will allow fordecreased treatment related complications and improved outcomes. Machinelearning, artificial intelligence, and augmented intelligence can beapplied to the incoming monitoring data to predict patients who aredeclining clinically or who are at risk of a major illness andhospitalization. These algorithms can alert the patients, theirfamilies, and their care teams and early interventions can beimplemented with the aim of preventing complications and unnecessaryhospitalizations. These analytics can be paired with a mobile orweb-based application that allows patients to also enter subjective dataabout how they feel or symptoms they are experiencing.

Within this database, data will also preferably be anonymized for use inanalysis and evaluation regarding patterns of cancer care, adversereactions, treatment efficacy and other outcomes based or comparativeeffectiveness research. With enough ports in use, the database willprovide a representative cross section of cancer care throughout thecountry (and perhaps the world) and will give critical informationregarding outcomes of specific diseases, use of specific therapeutics,access to care, and adverse outcomes. This information will be useful togovernment organizations tasked with developing healthcare policy andregulating pharmaceuticals and medical devices, academics performingcancer and rare disease research, pharmaceutical companies evaluatingthe use of their and their competitors' products, marketingorganizations involved in selling therapeutics, and financialorganizations tasked with investing in medical companies and allocatingcapital to emerging technologies.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will now be described in detail hereinafter byreference to the accompanying drawings. The invention is not intended tobe limited to the embodiments described; rather, this detaileddescription is provided to enable any person skilled in the art to makeand practice the invention.

One aspect of the invention relates to implantable port devices havinglow profiles to reduce the patient's discomfort and visibility.Preferably, a low profile implantable medication port that is nearlyimperceptible by the patient or others and can be localizedelectronically despite its low profile.

Current ports are identified and located via palpation of the patientchest region by the medical professional. That is, implant access isobtained by locating the port under the skin of the patient's chest andinserting a non-coring needle through the silicon diaphragm and into theport reservoir.

In order to ensure localization via palpation, current ports have a tallprofile that causes protrusion of the skin of the chest. This protrusioncauses discomfort for patients, is a constant reminder of their canceror other medical problems, and is not cosmetically appealing.

Comparing the implant device IO in FIG. 1 and device 20 in 2A, thedevice 20 shown in FIG. 2A has a lower profile allowing the implantdevice to have a lower visible profile in the patient reducingdiscomfort and other complications. According to the invention, theimplant devices are designed to have a lower profile while stillproviding at least one reservoir within the cavity of the device (e.g.,by using round disc-like shapes, thinner housing components, improvedconfiguration and/or design, etc.). Moreover, according to preferredembodiments, the low profile devices include electronics allowing theimplanted devices to be located despite having a low profile.

Preferably, the reservoir comprises a housing made from biocompatibleplastic or other polymer, an MRI safe metal such as titanium, or somecombination thereof, but is preferably sufficiently rigid on itsdeep/posterior and lateral portions thereof, and, preferably, cannot bepunctured by a medical needle. The posterior and lateral rigidity mayalso be achieved in a flexible, conformable reservoir with a honeycombor lattice internal structure.

The reservoir preferably further comprises a cap disposed at thesuperficial/anterior margin that can easily withstand multiple needleaccesses and have self-sealing properties. This cap is preferably madefrom silicone or a similar deformable, self-sealing, biocompatiblematerial. The reservoir preferably is only sufficiently tall for receiptof a port access needle, but has a low enough profile as to be nearlyimperceptible by the patient or others when implanted under the skin andsubcutaneous tissues. It is envisioned that the reservoir will be roundand generally shaped like a disc, but it is within the scope of thisinvention for the reservoir to take any shape that allows properfunction.

One embodiment relates to a medical implantable port device adapted forintravenous medication administration, the device comprising:

According to preferred embodiments, the ratio is greater than 3.5, morepreferably greater than 4, and even more preferably greater than 4.5.

Preferably, the device further comprises at least one catheter in fluidcommunication with the first fluid cavity.

Referring to FIG. 2A and FIG. 2B, the components of the port device 20include a rigid reservoir housing 22 comprised of biocompatible plastic,metal, or other material that provides rigidity and strength to preventneedle puncture. The reservoir housing 22 preferably is short instature, or low-profile, as to make it nearly unnoticeable to and/ormore comfortable for the patient. The reservoir housing 22 is hollow,providing at least one reservoir therein for holding pharmaceuticals ordrugs or related materials to be flushed forward into the central venoussystem. The reservoir (not shown) is covered by a cap or diaphragm 21that allows receipt of an access needle or catheter (not shown in FIGS.2A and 2B). This cap 21 is preferably made from silicone or a similarself-sealing material that allows for multiple needle access procedures.Preferably, in fluid communication with the reservoir is an attachedcatheter 23. Once inserted surgically, the catheter tip rests in acentral venous structure such as the superior vena cava or right atriumand is in fluid communication with the central venous blood.

Moreover, it is believed current ports on the market do not contain anyadvanced technology beyond those required for vascular access andmedication administration. Specifically, there are no means ofelectronic identification of the device or the patient, or localizationof the device. Additionally, it is believed, current ports have notechnology that allows for physiologic monitoring of the patient. Giventhe risks associated with improper patient identification or medicationadministration as well as the risk of clinical deterioration, applicantshave discovered it would be beneficial for an indwelling port to containadvanced electronic identification and monitoring technology with thecapability of transmitting data to a server-based computing platform,such as an electronic medical record (EMR).

Preferably, within or attached to the reservoir, but preferably not influid communication with the blood stream, is an electronic identifierand data storage device. Preferably, device will comprise one or moreradio-frequency identification (RFID) tag(s). Using an appropriatelydesigned electronic detector (e.g., handheld device), RFID tags can beeasily located with a high degree of precision. RFID tags can also carryinformation about the device and the patient. The identifier port devicepreferably comprises a single, centrally located RFID tag, and/or anRFID array utilizing multiple tags.

The aforementioned RFID tags could be either “passive” RFID tags thatrequire remote activation and power, or “active” RFID tags. Active RFIDtags would require a power source to be imbedded within the device,preferably in the form of a long-lasting battery capable of remote orinductive recharging. In conjunction with the RFID tags and/or abattery, the port preferably includes additional physical and electronicsensors or detectors that can measure, store, analyze, and transmitphysiologic data about the patient. These additional sensors mayidentify, monitor, and communicate patient information byelectromagnetic, acoustic, motion, optical, thermal, or biochemicaldevices or means. Electromagnetic devices or means include impedance,voltage, current, or magnetic field sensing capability with a wire,wires, wire bundle, magnetic node, or array of nodes. Acoustic devicesor acoustic means include sound frequency, within human auditory rangeor below or above frequencies of human auditory range, beat or pulsepattern, tonal pitch melody or song. Motion devices or means includevibration, movement pulse, pattern or rhythm of movement, intensity ofmovement, or speed of movement. Motion communication may occur by arecognizable response to a signal. This response may be by vibration,pulse, movement pattern, direction, acceleration, or rate of movement.Motion communication may also be by lack of response, in which case aphysical signal, vibration, or bump to the environment yields a motionresponse in the surrounding tissue that can be distinguished from themotion response of the device. Motion communication may also be bycharacteristic input signal and responding resonance. Optical devices ormeans include illuminating light wavelength, light intensity, on/offlight pulse frequency, on/off light pulse pattern, passive glow oractive glow when illuminated with special light such as UV or “blacklight”, or display of recognizable shapes or characters. It alsoincludes characterization by spectroscopy, interferometry, response toinfrared illumination, or optical coherence tomography. Thermal devicesor means include distinction of device temperature relative tosurrounding environment, temperature of device, temperature ofenvironment surrounding device, or differential rate of devicetemperature change relative to surroundings when device environment isheated or cooled by external means.
